1. Describe
AMIS30543C5431RG is a micro-stepping stepper motor driver for Bipolar stepper motor. The chip uses I/O pins and a SPI interface with external microcontroller. It has an on-chip Voltage regulator, reset output and watchdog reset, can provide peripheral equipment. AMIS-30543 includes a current conversion table And take the next microstep based on the clock signal The status of the "NXT" input pin and the "DIR" (=direction) register or Input pin. The chip provides the so-called "speed and load angle" Output. This allows the creation of stall detection algorithms and A control loop based on the load angle adjusts the torque and speed. this is Use a proprietary PWM algorithm for reliable current control. AMIS-30543 adopts I2T100 technology to realize High-voltage analog circuits and digital functions The same chip. The chip is fully compatible with automotive voltage Require. AMIS-30543 is very suitable for general stepper motors Motor applications in automotive, industrial, medical, and marine applications environment. Through the on-chip voltage regulator, it further reduces BOM for electromechanical stepping applications.
